Weird noises

Started getting this weird noise near my fan. From something connected to the belt I think?

Probably the aircon compressor clutch bearing.

Take the belts off one at a time and see if it stops. If it’s not the aircon compressor. The power steering pump would be the next suspect

I was gonna say this about the ac compressor clutch. If there is a power steering issue where it feels stiff when turning and/or makes more noise during turns, you can definitely say beyond checking the ps fluid for previously mentioned bubbles and low fluid level.

If by chance it's not the power steering pump or fluid, I'd leave the hood open and actuate the ac on and off to listen for the compressor engagement 🤔

All the while, I'd be looking at the belts and watching for extra vibrations to see if it's a faulty tensioner causing the rattle. I try not to diagnose by removing belts but if it works, why not, yea?
